Song features during the breeding season are important in identifying species of cuckoos. Whether Oriental Cuckoo Cuculus optatus and Himalayan Cuckoo C. saturatus inhabiting the Palearctic and Oriental realms respectively can be distinguished according to song characteristics is uncertain. In this study, we performed a thorough investigation of the song characteristics of these taxa by collecting and analyzing recordings of song in their distribution areas. We found that songs could be divided into two groups based on the number of notes per syllable, and significant differences in other frequency and temporal features were also found between these two groups. The group with a song comprising two notes per syllable was shown to breed in Russia, northern Xinjiang, northeast China, Taiwan Island and Japan, while the group with a song containing more than two notes per syllable was found to breed in the Himalayas and central China, extending northeast through north China as far as northeast Hebei, and south to southwest China. The distribution of these two groups was broadly related to the published distribution of populations of optatus and saturatus, respectively. Our data supported the separation of optatus and saturatus based on their song features, and also suggested refinements to the distribution of these two taxa, as follows: birds in north China are saturatus, and those in Taiwan Island are optatus. © 2016, Academia Sinica.

There are many opportunities available to improve the efficiency of your operation, and most equipment suppliers can help you exceed your specific requirements. With rising energy costs and tighter profit margins, everyone should be looking at ways to maximize the efficiency of their reclaim operations. Properly designed process cooling, material handling and size reduction systems are as important to the productivity of the plant as the extrusion technology itself. The analogy that "a chain is as strong as its weakest link" applies to all plastic processes as well. You don't want a million dollar molding machine or extrusion line sitting idle because you saved $5,000 when you bought your chiller or material handling system! You also don't want to spend any more money than necessary to re-process your material, so an energy-efficient system should be in your future plans!. Source
